The physical examination and dynamic ultrasound revealed the snapping of the sciatic nerve (SN) provoked by impingement between the greater trochanter (GT) and the ischium. Additional imaging studies demonstrated hyperintense signal in the SN at the hip, sagittal imbalance, decreased ischiofemoral space, and increased femoral torsion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Snapping and entrapment of the SN provoked by impingement between the GT and the ischium should be considered in the differential diagnosis of snapping hip and\/or sciatica.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2106\/jbjs.cc.20.00014","type":"journal-article","created":{"date-parts":[[2020,7,24]],"date-time":"2020-07-24T11:00:13Z","timestamp":1595588413000},"page":"e20.00014-e20.00014","source":"Crossref","is-referenced-by-count":13,"title":["Snapping of the Sciatic Nerve and Sciatica Provoked by Impingement Between the Greater Trochanter and Ischium"],"prefix":"10.2106","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4122-7845","authenticated-orcid":false,"given":"Munif","family":"Hatem","sequence":"first","affiliation":[{"name":"Hip Preservation Center, Baylor University Medical Center at Dallas, Dallas, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8719-2214","authenticated-orcid":false,"given":"Hal David","family":"Martin","sequence":"additional","affiliation":[{"name":"Hip Preservation Center, Baylor University Medical Center at Dallas, Dallas, Texas"},{"name":"Oklahoma State University, Stillwater, Oklahoma"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc R.","family":"Safran","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford University Medical Center, Redwood City, California"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2020]]},"reference":[{"issue":"1","key":"bib1-20230720","doi-asserted-by":"crossref","first-page":"186","DOI":"10.2214\/AJR.08.2090","article-title":"Ischiofemoral impingement syndrome: an entity with hip pain and abnormalities of the quadratus femoris muscle","volume":"193","author":"Torriani","year":"2009","journal-title":"AJR Am J Roentgenol."},{"issue":"10","key":"bib2-20230720","doi-asserted-by":"crossref","first-page":"1300","DOI":"10.1302\/0301-620X.93B10.26714","article-title":"Ischiofemoral impingement","volume":"93","author":"Stafford","year":"2011","journal-title":"J Bone Joint Surg Br."},{"issue":"2","key":"bib3-20230720","doi-asserted-by":"crossref","first-page":"239","DOI":"10.1016\/j.arthro.2014.07.031","article-title":"Diagnosis and 2-year outcomes of endoscopic treatment for ischiofemoral impingement","volume":"31","author":"Hatem","year":"2015","journal-title":"Arthroscopy."},{"issue":"2","key":"bib4-20230720","doi-asserted-by":"crossref","first-page":"268","DOI":"10.2106\/00004623-197759020-00028","article-title":"Impingement of the lesser trochanter on the ischial ramus after total hip arthroplasty.
